Robot gripper control system using PVDF piezoelectric sensors
… gripper control system is presented which uses PVDF piezoelectric sensors to actively damp exerted force. By using a low-input-resistance amplifier to sense the current developed by the PVDF sensor, an output proportional to the rate of change of the force exerted by the gripper is obtained. The …

Characterization of Nanoporous Polyvinylidene Fluoride (PVDF) Sensors under Tensile Loading
… piezoelectricity, a Polyvinylidene Fluoride (PVDF) sensor with integrating nanoporous structures was developed and fabricated. Several sets of samples with different porosities from 0% to 42.0% were made. The porosity effect on the sensor samples was studied under tensile loading, and the …

Actuator and sensor design and modeling for structural acoustic control
… performance prediction of shaped and distributed sensors and actuators for structural acoustic control. Sensor and actuator design was found to be sensitive to nodeline discrepancies between the model and experiment caused by moderate manufacturing defects and/or boundary condition uncertainties. …

Detection of in-plane stress waves with Polyvinylidene Fluoride (PVDF) sensors
<p>Polyvinylidene Fluoride (PVDF), a piezoelectric polymer, is an excellent stress sensor. The objective of this research is to investigate the application of the PVDF sensors for detection of in-plane stress waves in 31 and 32 modes. This was achieved by focusing on aspects of PVDF sensing related …

Development and characterization of a hydrogen peroxide sensor using catalase immobilized on a pyroelectric poly(vinylidene fluoride) film
… polymer film, poly(vinylidene fluoride) or PVDF. The sample is introduced into the flow channel using flow injection analysis technology. The heat from the reaction causes the pyroelectric material to produce an electrical potential proportional to the change in temperature which, in turn, …
